Answer:
A stroke is a loss of blood flow to a certain part of the brain. The resulting damage depends on the location and extensiveness of the stroke. A stroke to the left side of the brain will affect cognitive, motor and sensory areas. Language, thinking, behavior and physical movement can be impaired. Stroke is the third most common cause of death and is the main cause of disability among adults.
For most people, the primary language center is located on the left side of the brain. The American Stroke Association explains that a stroke in this area can cause either temporary or permanent impaired language ability. Not only can a person’s speech ability be affected, but the ability to read and write as well. Aphasia, the inability to use or comprehend language, agraphia, difficulty with writing words, and alexia, difficulty with reading, are all possible effects of a left-sided stroke.

a. A translation stop codon is added at the 3' end of the pre-mRNA.
c. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
d. Coding sequences called exons are spliced out by ribosomes.
Explanation:
In eukaryotes, during protein synthesis, the RNA must exit nucleus through the pores on the nuclear membrane and enter into the cytoplasm to undergo translation.
The exit processes of mRNA are: the 5’ capping, 3’ Poly-A tail, and pre-mRNA splicing.
The 5’capping is the initial step with addition of 7-methylguanosine cap to the 5’ end of the mRNA by phosphate linkage. This process protects the mRNA from degrading and helps to initiate translation processes.
The 3’ Poly-A tail step is the cleaving of pre-mRNA and addition of addition of around 200 A nucleotides or the 3’poly (A) tail to the mRNA by the poly (A) polymerase enzyme protein complex. This prevents pre-mRNA degradation, facilitates movement of mRNA to the cytoplasm, and initiates translation.
Pre-mRNA splicing is done to remove the introns from the mRNA because they are not part of function protein coding. The exons which take part in protein coding sequence are spliced once the introns are excised.
Finally, the resultant mRNA will exit the nucleus and enter the cytoplasm to undergo translation

I believe the answer is: C. A pre-cut baking potato
Basically, every food that are 'enriched' with additional substance would most likely made in factory and could had additives on it in order to ensure it stay long on the store. same story goes with 'package foods' such as packaged crackers. Because of this, pre-cut baking potatoes are the healthier option.
You should continuously work to enhance your skills and knowledge
The answer is letter A.
There are some people who take illegal substances in the body as a result of an underlying insecurity or lack of emotional support. Some narcotic drugs out there are meant to suppress appetite which then causes people who are dependent on them to develop eating disorders. Stimulants like amphetamines cause an excessive change in behavior and eating habits which would result eventually to eating disorders. People who are known to have a substance abuse problem must always seek the help of professionals in order to resolve and regress past issues.
